MEANS FOR FORMING WIDE SHEDS OFWARP FROM NARROW R SHORT-SUPPLY-BEAMS.

SPECIFICATION forming part of Letters Patent no. 603,407, dated May 3,1898.

Application 1118a December 31,18 6. Serial no. 617,584. (No model.)

To all whom it may concern.-

Be it known that I, ISAAC E. PALMER, of. Middletown, in the county ofMiddlesex and object in view of rendering it feasible to ship the warpin a compact roll and at the same time render it feasible to weave goodsof any desired width from such compact warp-supply beam.

In the accompanying drawings, Figure 1 represents portions of a loom invertical section from front to rear for the purpose of showing theapplication of the warp-spreading device. Fig. 2 is a view in elevationlooking at the end of the -1oom from which the warp is fed. Fig. 3 is asimilar view showing a modified form of distributing-roll; and- Figs. 4and 5 represent, respectively, in end elevation and in vertical sectiona secon modification.

Referring to the form shown in Figs. 1 and 2, the loom as a whole isrepresented by A, the beam which finally distributes the warp to thegrid at of the loom is denoted by B, and the take-up beam by O. Thelattermay be driven'by any well-known or approved means. The Warp-supplybeam is denoted having end flanges d of sufficient diameterto renderthebeam of great capacity in proportion to its length, a form which isfound more practical for storage and shipment than the more elongatedform.

The roller B, which finally distributes the warp to the grid 0,, isprovided with annular grooves bin its periphery, the space between thegrooves being rounded on their faces for the purpose of causing the warpto seek the grooves when pressed against the periphery.

Intermediate of the grooved roller B and the supply-beam D, I locate aplurality of distributing-rollers, in the present instance two,

and denoted,respectively,by E and E, mounted with their axes inclined tothe axis of the roller or beam D and also inclined with respect to eachother, the said axes gradually approaching the axis of the supply-beam Das they recede from the adjacent toward the opposite ends of the rolls EE, as clearly indicated in Fig. 2.

The warp (denoted by F) on the supplybeam Dis separated as it leaves thesupplybeam into subdivisions ff, which are led to and over the inclinedrollers E E, respectively, and thence to the distributing roller or beamB, where the two subdivisions f f are so spread in the grooves of theroller B as to engage it throughout its length. The subdivisions of thewarp having once been distributed along the length of the distributingroller or beam B tend thereafter to retain their position along the beamB without further attention by gradually creeping into the successivegrooves in the periphery of the roller B, and from this point they leadwith sufficient directness to the grid at, which finally completes theirseparation for pur poses of weaving.

, Instead of providing the grooved beam 19 the subdivisions ff may beled from the inclined rollers E E to arched rollers e e, preferably' setat a slight angle of inclination to one another, as clearly shown inFig. 3. The arched rollers e e are mounted upon fixed arched spindles GG and are formed of some suitable flexible material-such, for example,

as gutta-perchain the form commonly employed as rubber hose. .of suchyielding material will accommodate by D and is here shown in the form ofa spool The roller formed itself to the curved spindle as it is rotatedon the spindle by the friction of the Warp, the arched or crown shape ofthe roller serving to distribute the threads of warp from the center ofthe arch toward its extremities as it is led from the arched rollers tothe grid.

In the form shown in Figs. 4 and 5 the warp F is fed directly from thesupply-beam D to an arched roller e which is here arranged to take theplace of two inclined rollers E E, and is mounted upon a fixed archedspindle G The roller e like the rollers e 6 herein above described, isformed of some suitable flexible materialsuch, for example, as that usedfor rubber hose-and because of its flexible nature it will accommodateitself to the arched spindle G as it is rotated thereon by the frictionof the warp. In this arrangement the warp-threads, after having beenspread by passing over the arch or crown roller 6 are directed to thegrid on by means of the guide-roller B, which in this instance may be anordinary plain-faced roller.

The rollers 13 and B are so located with respect to the inclineddistributing-rollers and the supply-beam as to retain the warp inengagement with their faces.

It is obvious that slight changes may be resorted to in the form andarrangement of the several parts without departing from the spirit andscope of my invention. Hence I do not wish to limit myself strictly tothe structures herein shown and described; but

What I claim is 1. The combination with a grid and warpsupply beam, ofmechanism for distributing warp as it extends from the supply-beam toform a shed wider than the length of the supply-beam, comprising, adistributing device located intermediate of the grid and thesupply-beam, said distributing device being provided with a warp-bearingsurface which gradually approaches the axis of the warp-beam as itextends from a point opposite a central portion of the warp-beam towardits extremities and means for holding the warp in engagement with thesurface of the distributing device and directing it to the grid,substantially as set forth.

2. In combination a warp-supply beam, distributing-rollers having theiraxes inclined to the axis of the warp-supply beam for distributing thewarp as it ex tends from the beam and means for holding the warp inengagement with the distributing-rollers, substantially as set forth.

In combination a warp-supply beam, a grid, distributing-rollers havingtheir axes inclined to the axis of the warp-supply beam for distributingthe warp as it extends from the beam and means for further distributingthe warp afterit leaves the said inclined distributing-rollers andbefore it reaches the grid, substantially as set forth.

4. The combination with an arched spindle and means for holding it infixed position, of a roller of flexible material mounted on the archedspindle and means for directing warp along the surface of said roller inengagement therewith for distributing the warp, substantially as setforth.
